TaxJar vs. Avalara: which is better for ecommerce?

If you’re evaluating both TaxJar and Avalara, here’s the honest answer: they’re built for different businesses, and neither one is the clear winner for the mid-market ecommerce seller who’s growing fast and doesn’t have an internal tax team.

TaxJar was built for simplicity. Avalara was built for scale. Both have trade-offs that matter, and there’s a structural limitation they share that most comparison articles won’t mention.

Where each platform is actually built for

TaxJar is made for small sellers who want to plug something in, get it working, and not think about it too hard. Clean UI. Straightforward Shopify integration. At low filing volume, the pricing is reasonable. That was the product before Stripe acquired it in 2021. Post-acquisition, the product has drifted toward Stripe’s priorities, pricing has increased, and support has thinned out.

Avalara is made for large companies. Multi-entity. Global. NetSuite. SAP. Dedicated tax ops team that can manage the implementation. If that’s you, Avalara is the right tool. If you’re a $10M Shopify brand where the “finance team” is a controller and a bookkeeper — Avalara is a lot of complexity for a problem that doesn’t require it.

What each one costs

Avalara’s pricing opacity is a consistent complaint across G2 reviews. “1,000% price increase” and “jacked up the price” are recurring phrases from former Avalara customers in public reviews. You won’t know what you’re paying until you’re already committed.

What each one is like to use

TaxJar’s ease of use rating on G2 is 9.2 out of 10. Avalara’s is 7.8. That gap is real. TaxJar is genuinely simpler to set up and navigate for a seller who isn’t a tax professional. Avalara requires real work, often paid implementation work on top of the subscription.

One customer described spending $5,000 with an outside contractor to get Avalara set up because “the Avalara implementation team was outsourced and nearly zero help.” That’s not unusual.

What each one is like when something goes wrong

This is where both platforms have documented problems, for different reasons.

Avalara’s support problem is structural: outsourced overseas, slow escalation, frequent unresolved tickets. Customer reviews describe it as “horrendous,” “goes to a bot,” and “overseas.” One reviewer was charged $6,300 by Avalara support to restore tax calculations after a miscommunication.

TaxJar’s support problem is post-acquisition: it’s self-service only now. Response times run 3–5 days. One customer documented returns that AutoFile marked as “filed” where taxes were never actually remitted, and couldn’t reach anyone to resolve it quickly.

Both are a problem if you’re a lean team that can’t absorb support friction.

The structural gap both share

Neither TaxJar nor Avalara (in practice) maximizes the Streamlined Sales Tax program for qualifying sellers.

• TaxJar is not a CSP at all. No SST-funded free filing, ever.
• Avalara is a CSP but charges $42–65/state even for SST states where that filing could be covered by the program.

For a growing ecommerce brand filing in SST member states and qualifying as a remote seller, both platforms are charging fees that could be $0 under active CSP enrollment. It’s worth understanding this before committing to either.

Who should use TaxJar

• Shopify SMBs who want simple, self-managed compliance
• Stripe-native sellers who benefit from the TaxJar/Stripe integration
• Sellers filing in fewer than 5–6 states who don’t have SST exposure that moves the needle

Who should use Avalara

• Multi-entity businesses with SAP, NetSuite, or Oracle requirements
• Companies with international revenue that needs VAT/GST alongside US sales tax
• Large organizations with a dedicated tax team that can handle the onboarding and ongoing management

Who should look at a third option

If you’re a $10M–$100M ecommerce brand on Shopify with nexus in multiple SST states, running a lean ops team, you’re not TaxJar’s ideal customer anymore (post-Stripe, they’ve narrowed toward smaller, Stripe-first buyers) and you’re not Avalara’s ideal customer either (you don’t need the enterprise infrastructure). There are platforms built specifically for this profile.

TaxCloud is the most direct comparison. It’s a Certified Service Provider in the SST program — qualifying remote sellers get filing in 24 SST states included at no additional charge. It’s built for growing ecommerce brands in the $10M–$100M range, with native integrations for Shopify Plus, BigCommerce, and WooCommerce, and US-based support that answers the phone. TaxCloud is also the highest rated sales tax platform on the Shopify App Store, with 90+ five-star reviews. For sellers with meaningful SST-state nexus, the cost math looks materially different than with either platform above.
